I don't get what's wrong with this, this was perfectly normal for over a million years.
Only in our recent "modern" times has it changed, but it will be changing back very soon!
@newmangaread246 I thought the same thing of Aho Girl at first too but it somehow became bearable but it turned alright at the end right?
Have you not read that Manga with a hundred girlfriends? Hilarious romcom but also it gets weird af later on though, idk if it's still worth reading (His mother in law in the harem too)
